if() statement no longer working. Anything wrong on my end?

[alexander_torre]

Hi, 

I've had a report with a dimension (if() statement) that's been working fine for the past year until today. I received an Error with the if statement.

Current if statement for the dimension:

if(table.column = "A + B", 0, 1)

It just now stopped working, and I am getting errors for all reports. Was there an update to Looker or an update on our DB?

Thanks for any help!!

Figured out another way to get the dimension I wanted. Looker no longer allows the type(tier, string) combo I initially had for the if statement.
